Write two uses of Mercury
and zinc.
Answers
Answer:
Mercury used in batteries, fluorescent lights, felt production, thermometers and barometers. Again, these uses have been phased out. Mercury easily forms alloys, called amalgams, with other metals such as gold, silver and tin.
Zinc is also used in alloys such as brass, nickel silver and aluminium solder. Zinc oxide is widely used in the manufacture of very many products such as paints, rubber, cosmetics, pharmaceuticals, plastics, inks, soaps, batteries, textiles and electrical equipment.

Summary
This chapter discusses the history, abundance, distribution, and production of zinc, cadmium, and mercury. The major ores of zinc are zinc sulfide and zinc carbonate. Cadmium is found as greenockite, but its only commercially important source is the 0.2–0.4% found in most zinc ores. Cinnabar is the only important ore and source of mercury, which is found along the lines of previous volcanic activity. The chapter provides an overview of the applications and the uses of zinc, cadmium, and mercury. Zinc finds a wide range of uses. The most important is as an anticorrosion coating. Zinc sheeting is also used in roof cladding and in manufacturing of dry batteries. The major uses of cadmium are in batteries and coatings. The chapter also discusses the physical properties, chemical reactivity, and group trends of zinc, cadmium, and mercury. The most noticeable features of zinc, cadmium, and mercury are their low melting and boiling points. Mercury, in a liquid state at room temperature, is unique as a metal. Zinc and cadmium are silvery solids with a bluish luster when freshly formed. Mercury is also unusual in being the only element, apart from the noble gases, whose vapor is almost entirely monatomic.
